Abstract: A method and apparatus for securing snow tire chains to tires. Two cables are secured to snow tire chains secured about at least one tire utilizing a securing mechanism. The two cables are secured to the securing mechanism utilizing a connecting mechanism integrated with the securing mechanism. The cables are connected to the snow tire chains by a tensioning mechanism integrated with the securing mechanism. The securing mechanism is centrally mounted along a side of the tire. The securing mechanism can be configured with a chamber for receiving the cables within the securing mechanism. The tension mechanism is generally centrally located within the securing mechanism. The cables can be attached to the snow tire chains utilizing an attachment mechanism.

Abstract: The present invention relates to the isolation of gene sequences encoding mammalian cell cycle checkpoints, as well as the expression of the encoded proteins using recombinant DNA technology. The expressed proteins are used to generate specific antibodies and to inhibit the growth of cells. The human checkpoint gene sequences are used as a probe for a portion of the chromosome associated with tumors and other malignancies, as well as growth and/or development deficiencies.

Abstract: The present invention provides an apparatus, method and system for managing investments having one or more characteristics. The present invention creates three or more investment agents, each investment agent having one or more characteristics, and selects an investment for each investment agent by comparing the investment agent's one or more characteristics to the investment's one or more characteristics. The selected investment for each investment agent is then acquired if the selected investment is not currently owned by the investment agent.

Abstract: An apparatus and method for controlling the plasma potential of a plasma within a plasma chamber (50) is disclosed. The apparatus and method utilize a Faraday shielded inductive source antenna (60) to generate the plasma within the plasma chamber (50) and an electrically conductive probe (100) that is inserted into the plasma chamber (50) to regulate the plasma potential. By independent biasing of the conductive probe (100), which regulates the plasma potential, the ion energy distribution at a conductive substrate (150) within the plasma chamber (50) may be controlled.

Abstract: A seismic handling device for safely transporting, deploying, and retrieving a seismic unit on a sea vessel is disclosed. The seismic handling device comprises a plurality of vertical structural members extending from the vessel. A plurality of horizontal structural members are connected to the vertical structural members. A delivery system is securely attached to the horizontal structural members. The delivery system positions the seismic unit into the sea, tows the seismic unit during a survey and retrieves the seismic unit from the sea.

Abstract: An apparatus for attaching a sand-control screen jacket to a base pipe comprising a base pipe connector securably engaged with the sand-control screen jacket, an internal slip member slidably disposed between the base pipe connector and the base pipe and a jam nut securably engaging the base pipe connector such that the internal slip member slides toward the base pipe connector increasing the friction between the internal slip member and the base pipe, thereby securing the sand-control screen jacket to the base pipe. The base pipe connector may further comprises a plurality of sealant ports through which sealant is injected affecting an additional seal between the base pipe connector and the base pipe. The sealant ports may accept a lock pin therein after sealant is injected.

Abstract: A well tool apparatus (40) comprising a tubular housing (56) and operating mandrel (58) each having autofill ports (74, 76) and bypass ports (128, 130) therein. The well tool apparatus (40) also comprising a normally closed ball valve (96) rotatably disposed within the operating mandrel (58) preventing communication between the upper section (104) and the lower section (106) of the operating mandrel (58) such that internal pressure above the ball valve (96) greater than internal pressure below the ball valve (96) downwardly urges the operating mandrel (58) allowing pressure testing of the pipe string (32) above the ball valve (96) and such that internal pressure below the ball valve (96) greater than internal pressure above ball valve (96) upwardly urges the operating mandrel (58).

Abstract: A system is provided for selectively perforating multiple zones in a well either simultaneously, or in series, having isolation barriers, or packers, located between the perforating multiple zones, without moving the system with respect to the well. The system includes a tubing string which carries at least a first and a second perforating gun. At least a first and a second pressure actuated firing head are associated with the first and second perforating guns, respectively. A first and second packer for isolating the perforating guns from each other. A source of actuating fluid pressure for the firing head is provided, which may be the bore of the tubing string. A first selective communication device is provided for isolating the second firing head from the source of actuating fluid pressure until after the first perforating gun has been fired, and for then communicating the second firing head with the source of actuating fluid pressure in response to firing of the first perforating gun.
